Backups dont delete older versions

This setting has no effect:
Select Backup Retention. Leave 0 for no limit

I place a value of anything in there 7 for example and there is no backups deleted - it just fills up the hard drive and all the problems associated with a full hard drive come up.

Is there a fix for this?

Hello users,

when I search for this topic I dont find a solution.

so either I am poor at searching

Its already been covered - if yes please send me a link to read about it

this is an isolated problem ( doubtful because its the same on each CP server)

or this feature is not widely used…
